Eagle Eye,
I would say go ahead and settle on the 30D because it's a good camera and there's no need to think about a 20D since the 30D is now in bargain territory. Then relax, take a deep breath, and thing about a lens.
You say you want a good telephoto lens, which hobbiests want (as well as a macro lens!) so this might in fact be your toughest decision! Bargain lenses are low quality compared to "good" lenses, which will likely cost more than your priced-down 30D.
I'm just suggesting that you'll get a good deal these days on a great camera due to the next model being released and you are not accepting low quality. Thing about your lenses, and buy the best you can afford, because they will get the best out of not just the 30D but each body you upgrade to.
Just my thoughts!
Tony
